Explores principles and types of moondials, including tabular, volvelle, graphical and adjustable designs. Analyses moon’s orbital motion, parallax, illumination, and visual limitations under moonlight. Proposes improvements to enhance accuracy towards that of simple sundials, and presents prototype experimental dials demonstrating refined timekeeping performance.

Details construction of a combined equatorial and equinoctial sundial using stacked car engine starter rings, cylindrical and brass components. Describes adjustable latitude setting and a novel gearing mechanism employing concentric eccentric spindles to apply the equation of time correction on two knobs, enabling mean time readings without manual calculation.

Examines the sundial ensemble in the courtyard of Cascina Picchetta, a 17th-century Italian villa. Analyses six wall-mounted sundials across two façades with varying hour systems (Italian, Babylonian, French, temporary), equatorial orientations, declination corrections, and historical decorative motifs. Explores Jesuit influences and conservation considerations.

Reassesses the original Anglo-Saxon sundial at St Mary’s, Stoke D’Abernon through newly discovered early photographs. Reveals the dial’s inclined face, previously unrecognized, and reviews past interpretations. Discusses typological features of Saxon angled-gnomon dials, date uncertainty, and implications for correct dating and classification.

Narrates the British Sundial Society’s 2004 tour of Italy, detailing visits to Rome, Florence and Ravenna. Highlights significant sundials and meridian installations, including the Palazzo Spada ceiling dial, Pantheon meridian, San Petronio line, the La Meridiana villa and private designs. Describes historical context, local hosts, and field observations of classical gnomonic art.

Analyses a rare Italian pillar dial in Ravenna with a horizontal gnomon, calibrated for reading the time in the Italian hours system at solar noon. Discusses calculating local noon offsets, latitude influences, and historical context of Venetian installation. Examines missing gnomon, hurricane damage and the cultural practice of hour counting from event-based day start.
